Intel Pentium III 600E
Pentium 4 1.x GHz
The 600E is equipped with a Coppermine core; a significant improvement, but not as much as the 600EB, over the old Katmai core (The 600 and 600B; the latter uses a 133MHz FSB). The Katmai at 600MHz had a TDP of 42W whereas the Coppermine was satisfied with just 15.8W. Not to mention the cheaper manufacturing costs due to a smaller but faster on-die L2-cache and an overall smaller chip as result of a die-shrink.
